Description

Technical Field

[0001] This utility model relates to the field of oil pipeline processing technology, specifically to an adjustable oil pipeline welding device. Background Technology

[0002] Petroleum is a viscous, dark brown liquid, often referred to as the "blood of industry." It is found in certain areas of the Earth's upper crust. Its main components are a mixture of various alkanes, cycloalkanes, and aromatic hydrocarbons. It is a primary target for geological exploration, and after extraction, it needs to be transported long distances to various locations via pipelines.

[0003] During the production and processing of oil pipelines, multiple short pipes need to be welded end to end to increase the length of the pipeline. The welding process involves first butt-jointing the ends of the oil pipelines, then securing them with a fixing mechanism, and finally welding the joints. Current oil pipeline welding equipment uses welding or bolts to directly fix the fixing mechanism to the frame, making it difficult to adjust the spacing between adjacent fixing mechanisms. This results in difficulties in fixing short pipes of different sizes when welding them.

[0004] In view of this, there is an urgent need for an adjustable oil pipeline welding device to overcome the shortcomings of the existing technology. Utility Model Content

[0005] To address the problems existing in the prior art, this utility model solves the problem using the following technical structure.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] An adjustable oil pipeline welding device includes: a frame, a welding mechanism, and several fixing mechanisms;

[0008] The frame is provided with a first slide rail extending along a straight line. The first slide rail is a linear slide rail, and several of the fixing mechanisms are slidably disposed on the first slide rail.

[0009] The fixing mechanism includes a first mounting base, a short pipe fixing component disposed on the first mounting base, and a first fixing component. The short pipe fixing component is used to fix the short pipe so that the short pipe is in a horizontal state. The first mounting base is slidably disposed on the first slide rail, and the first fixing component is used to lock the first mounting base on the first slide rail.

[0010] The welding mechanism is slidably disposed on one side of the plurality of fixed mechanisms, and the welding mechanism is used to weld the short pipe.

[0011] The frame is provided with a drive mechanism and an ejector mechanism. The drive mechanism includes a drive component and a clamping assembly. The clamping assembly and the ejector mechanism are respectively located on the side of the two outermost fixing mechanisms that are far apart from each other. The clamping assembly is used to clamp the short tube on the adjacent fixing mechanism, and the drive component is used to drive the clamping assembly to rotate.

[0012] The ejector mechanism is used to apply a thrust toward the clamping assembly side to the short tube on the adjacent fixing mechanism.

[0013] The first slide rail includes two parallel limiting plates, with the side of the two limiting plates close to each other being suspended in the air, and the first mounting base is disposed on the two limiting plates.

[0014] The first fixing component includes a fixing plate and a plurality of fixing bolts. The fixing plate is fixed to the bottom of the first mounting base by the plurality of fixing bolts. The two limiting plates are disposed between the fixing plate and the first mounting base on their sides that are close to each other.

[0015] A positioning strip is provided on one of the limiting plates, the positioning strip is aligned with the extension direction of the limiting plate, and a positioning groove adapted to the positioning strip is provided at the bottom of the first mounting base.

[0016] The short pipe fixing assembly includes a support platform, a cover plate, and a limiting component. The support platform is disposed on the top of the first mounting base. The support platform is provided with an upward-opening support groove. The cover plate is provided with a limiting groove. The limiting component is used to fix the cover plate on the support platform, so that the opening of the limiting groove is opposite to the opening of the support groove.

[0017] Both the support platform and the cover plate are provided with a number of rollers, and the rollers extend circumferentially into the support groove or the limiting groove.

[0018] The cover plate has a rotating end and a free end at its two ends, respectively. A first rotating shaft is provided on the support platform, and the rotating end is disposed on the first rotating shaft. The limiting component is used to fix the free end on the support platform.

[0019] The limiting component includes a limiting bolt, a rotating component is provided on the support platform, the limiting bolt is threadedly connected to the rotating component, and a U-shaped groove is provided on the free end.

[0020] A heating mechanism is provided between each of the two adjacent fixing mechanisms. The heating mechanism includes a second mounting base, a heat insulation pad, a heating plate, and a second fixing component. The second mounting base is slidably disposed on the first slide rail, and the second fixing component is used to lock the second mounting base to the two limiting plates.

[0021] The heat insulation pad is disposed at the top of the second mounting base, and the heating plate is disposed at the top of the heat insulation pad.

[0022] The above-described structure of this utility model can achieve the following beneficial effects:

Detailed Implementation

[0035] To enable those skilled in the art to better understand the present invention, the technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort should fall within the protection scope of the present invention.

[0036] It should be noted that the terms "comprising" and "having" and any variations thereof in the specification, claims and accompanying drawings of this utility model are intended to cover non-exclusive inclusion. For example, a process, method, apparatus, product or device that includes a series of steps or units is not necessarily limited to those steps or units that are explicitly listed, but may include other steps or units that are not explicitly listed or that are inherent to such processes, methods, products or devices.

[0037] The following is in conjunction with the appendix Figure 1-10 This application will be described in further detail.

[0038] refer to Figures 1-3An adjustable oil pipeline welding device is shown, comprising: a frame 1, on which a drive mechanism 2, a pin mechanism 3, a welding mechanism, and several fixing mechanisms 4 are mounted (the specific number is adaptively adjusted according to processing requirements; in this embodiment, nine are preferably provided, meaning nine short pipes are welded simultaneously); the several fixing mechanisms 4 are arranged sequentially along a straight line, and the fixing mechanisms 4 are used to fix the short pipes, keeping them in a horizontal state; the welding mechanism is slidably mounted on one side of the several fixing mechanisms 4 (the welding mechanism is driven to slide on one side of the several fixing mechanisms 4 by a drive component, not shown in the attached figure), and the welding mechanism is used to weld the short pipes; the drive mechanism 2 includes a drive component 21 and a clamping assembly 22, the clamping assembly 22 and the pin mechanism 3 are respectively mounted on the side of the two outermost fixing mechanisms 4 that are far apart from each other, the clamping assembly 22 is used to clamp the short pipes on adjacent fixing mechanisms 4, and the drive component 21 is used to drive the clamping assembly 22 to rotate; the pin mechanism 3 is mounted on the side of the two outermost fixing mechanisms 4 that are far apart from each other. Mechanism 3 is used to apply a thrust toward the clamping assembly 22 to the short pipes on the adjacent fixing mechanisms 4. Thus, during processing, each fixing mechanism 4 fixes a short pipe, and the clamping assembly 22 clamps the end of an adjacent short pipe. The ejector mechanism 3 applies a thrust toward the clamping assembly 22 to the short pipe, so that the ends of the short pipes on several fixing mechanisms 4 are in contact. Due to the consistency of the support height of several fixing mechanisms 4, the short pipes on several fixing mechanisms 4 are coaxial. Then, the welding mechanism welds the joints between adjacent short pipes in sequence. At the same time, the drive assembly 21 drives the clamping assembly 22 to rotate, so that the short pipes being welded rotate synchronously in the same direction. The welding mechanism welds the joints in sequence in the circumferential direction until the welding of the short pipes on several fixing mechanisms 4 is completed, so that several short pipes form a long oil pipeline. Fixing several short pipes at once before welding ensures that several short pipes are set coaxially, which is beneficial to improving the coaxiality of several short pipes and improving the welding efficiency of the oil pipeline.

[0039] like Figure 1 and Figure 2 As shown, in order to facilitate the adjustment of the position of the fixing mechanism 4, the frame 1 is provided with a first slide rail extending along a straight line. The first slide rail is a linear slide rail, and several fixing mechanisms 4 are slidably arranged on the first slide rail. In this embodiment, the first slide rail is composed of two parallel track plates 5. The two track plates 5 are suspended on the side that is close to each other. According to the welding requirements, the fixing mechanism 4 is slid on the two track plates 5 to adjust the distance between adjacent fixing mechanisms 4 to adapt to the welding of short pipes of different lengths.

[0040] like Figure 4As shown, in order to position several short tubes axially, the ejector mechanism 3 includes a sliding seat 31 and an ejector pin 32. The sliding seat 31 is set on the first slide rail, and the ejector pin 32 is horizontally rotatably set on the side of the sliding seat 31 close to the fixing mechanism 4. Thus, by pushing the sliding seat 31 to slide on the first slide rail, the ejector pin 32 is pressed against the end of an adjacent short tube, so that the ends of several short tubes are in contact. Then the sliding seat 31 is locked on the first slide rail. When the drive assembly 21 drives the short tube to rotate, the ejector pin 32 rotates relative to the sliding seat 31. Alternatively, a motor can be set on the sliding seat 31 to make the clamping assembly 22 and the ejector pin 32 rotate synchronously, so that the short tubes on both sides rotate synchronously.

[0041] like Figures 5-8 As shown, the fixing mechanism 4 includes a first mounting base 41, a support platform 42, a cover plate 43, a first fixing component, and a limiting component. The first mounting base 41 is slidably disposed on a first slide rail. The first fixing component is used to lock the first mounting base 41 onto the first slide rail. The support platform 42 is disposed on the top of the first mounting base 41 and has an upward-opening support groove 421. The cover plate 43 has a limiting groove 431. The limiting component is used to fix the cover plate 43 onto the support platform 42, so that the opening of the limiting groove 431 is opposite to the opening of the support groove 421. The short pipe is supported by the support platform 42, and the cover plate 43 is fixed on the support platform 42 by the limiting component, which limits the radial movement of the short pipe and completes the fixation of the short pipe position. The first mounting seat 41 is slidably set on the two track plates 5, which facilitates the adjustment of the position of the support platform 42. Furthermore, the support platform 42 and the cover plate 43 are provided with several rollers 44, which extend circumferentially into the support groove 421 or the limiting groove 431, so that the short pipe contacts the rollers 44, which facilitates the rotation of the short pipe for circumferential welding at the joint of adjacent short pipes.

[0042] like Figure 6 and Figure 7 As shown, the cover plate 43 has a rotating end and a free end at its two ends. A first rotating shaft 423 is provided on the support platform 42, and the rotating end is disposed on the first rotating shaft 423. A limiting component is used to fix the free end to the support platform 42. The limiting component includes a limiting bolt 45, and a rotating part 46 is provided on the support platform 42. The limiting bolt 45 is threadedly connected to the rotating part 46. A U-shaped groove 47 is provided on the free end. In this way, the cover plate 43 rotates on the support platform 42 without obstructing the support groove 42. The opening 1 facilitates placing the short pipe on the support platform 42 or removing the short pipe from the support platform 42; the setting of the limiting bolt 45 allows the rotating part 46 to rotate relative to the support platform 42 (rotating in a direction perpendicular to the horizontal plane) after the cover plate 43 is closed on the support platform 42, so that the limiting bolt 45 enters the slot 47, and then the limiting bolt 45 is rotated so that the nut of the limiting bolt 45 locks in the slot 47 on the side away from the support platform 42, thereby fixing the cover plate 43 on the support platform 42.

[0043] like Figure 7 As shown, in order to allow the first mounting base 41 to slide on the two track plates 5 and to be easily locked at a certain point on the track plates 5, the first fixing component includes a fixing plate 48 and several fixing bolts 49. The fixing plate 48 is fixed to the bottom of the first mounting base 41 by the several fixing bolts 49. The sides of the two track plates 5 that are close to each other are both located between the fixing plate 48 and the first mounting base 41. When it is necessary to adjust the position of the first mounting base 41, the several fixing bolts 49 are turned to increase the distance between the first mounting base 41 and the fixing plate 48, so that the first mounting base 41 can slide on the track plate 5. When it is necessary to lock the position of the first mounting base 41, the several fixing bolts 49 are turned in the opposite direction to clamp the fixing plate 48 and the first mounting base 41, fixing them on the upper and lower sides of the track plate 5, thus completing the locking of the position of the first mounting base 41.

[0044] Further optimizations include, for example Figure 2 As shown, a positioning strip 51 is provided on a track plate 5. The positioning strip 51 is aligned with the extension direction of the track plate 5. The bottom of the first mounting base 41 is provided with a positioning groove 411 that is adapted to the positioning strip 51. In this way, the positioning groove 411 is engaged with the positioning strip 51, thereby positioning and restricting the position of the first mounting base 41 in the second direction (the second direction is perpendicular to the extension direction of the first slide rail) and the position perpendicular to the first slide rail direction, so as to ensure that the short tubes on several fixing mechanisms 4 are coaxial.

[0045] like Figure 6 As shown, in order to increase the support area for the short pipe, a support plate 422 is provided on one side of the support platform 42. Correspondingly, a pressure plate 432 is provided on the same side of the cover plate 43 and the support plate 422. The pressure plate 432 cooperates with the support plate 422 to fix the short pipe.

[0046] like Figure 6 and Figure 7 As shown, in order to limit the rotation angle of the cover plate 43, a second rotating shaft 424 is provided on one side of the support platform 42. A limiting plate 6 is provided on the second rotating shaft 424. A straight limiting hole 61 is provided on the limiting plate 6. A limiting post 7 is provided on one side of the rotating end. The limiting post 7 is locked in the limiting hole 61. The axial direction of the first rotating shaft 423 is consistent with the axial direction of the second rotating shaft 424. The axis of the first rotating shaft 423 does not coincide with the axis of the second rotating shaft 424. Thus, when the cover plate 43 rotates, the limiting post 7 slides in the limiting hole 61. The end of the limiting hole 61 away from the second rotating shaft 424 is the limit position of the movement of the limiting post 7. That is, at this time, the cover plate 43 and the support platform 42 are at the maximum angle.

[0047] like Figure 5 and Figure 9As shown, a heating mechanism 8 is provided between each of the two adjacent fixing mechanisms 4. The heating mechanism 8 includes a second mounting base 81, a heat insulation pad 82, a heating plate 83, and a second fixing component. The second mounting base 81 is slidably mounted on the first slide rail. The second fixing component (the structure of the second fixing component is the same as that of the first fixing component, and will not be described in detail here) is used to lock the second mounting base 81 on the first slide rail. The heat insulation pad 82 is located at the top of the second mounting base 81, and the heating plate 83 is located at the top of the heat insulation pad 82. In order to improve welding efficiency and welding quality, a heating mechanism 8 is provided at the joint of two adjacent short pipes. Heating is performed by the heating mechanism 8 to increase the temperature at the joint, which facilitates welding. It also reduces the cooling rate, prevents cracks, reduces welding stress, and removes moisture.

[0048] like Figure 1 and Figure 10 As shown, a second slide rail is provided on one side of the first slide rail. The second slide rail is parallel to the first slide rail. A length measuring mechanism 9 is provided on the second slide rail. The length measuring mechanism 9 is used to measure the distance between the two outermost short pipes on the sides that are far apart from each other. The length measuring mechanism 9 includes a length measuring sensor 91. The sensor 91 detects the two outermost short pipes on the sides that are far apart from each other, thereby calculating the length of the entire oil pipeline.

[0049] The above are merely preferred embodiments of this application, and the present invention is not limited to the above embodiments. It is understood that other improvements and variations that can be directly derived or conceived by those skilled in the art without departing from the spirit and concept of the present invention should be considered to be included within the protection scope of the present invention.
